ADAMS : INTERESTING KENTISH FORMS. 319 
white below, which I propose to call efzzona ; albicans, alba 
with and without translucent bands. This field was on the 
slope of a little hill facing N.W.; at the bottom the shells 
were of the usual size, but they diminished as they ascended 
the slope till some very small ones were found (of all the 
above vars.) measuring 8 mm. in diameter. At the S. 
Foreland this species is always abundant, but exceptionally 
so this year; the shells were to be seen clustering on the 
thistle and hemlock stems as thickly as the 7. pesava on 
the ragwort at Tenby. At Brookland the gvescens and 
vufula-zonata forms occurred. 
H. terrestris. Under the guidance of Mr. Horsley I visited 
the colony of this southern form, and found it (like Z caz- 
tustana, Hf. virgata, &c.) aestivating on blades of grass. 
Mr. Horsley, who has visited the spot periodically since its 
discovery, says it is steadily increasing and extending its 
range. 
Pupa and Vertigo do not seem to appreciate Kent ; perhaps 
they find a difficulty in burrowing into the hard and 
dry chalk. 
Succinea putris. There is a picturesque old marsh between 
Sandwich and Richboro’, where, this year, the S. putrzs 
have surpassed themselves in size and numbers, many 
measured 19 mm., and some nearly 20 mm. 
Limnezea stagnalis and L. palustris. These two species 
swarm in the marshes and dykes from Brookland to Hythe, 
and in Minster Marsh. ‘This year they are almost 
invariably marked with white lines or “growth checks,” 
mentioned in Mr. ‘Taylor’s “ Monograph,” part i1., p. 83. 
It occurred to me that the dry season might have had 
something to do with the phenomenon, as in many cases 
the shells were crawling about on the dry mud. As, 
however, these marks are upon the upper whorls as much 
as on the lower, we must suppose that some were formed
